Why I Believe a Harley Crankcase Breather Kit is Essential

As a long-time Harley rider and enthusiast, I have experienced first-hand the importance of proper maintenance and performance enhancements for my bike. One crucial component that is often overlooked by riders is the crankcase breather system.

The crankcase breather system allows excess pressure and oil vapors to escape from the engine, preventing build-up and potential damage. However, the stock breather system on most Harley models is not very efficient, leading to oil leaks, reduced power, and even engine damage.

That’s where a Harley crankcase breather kit comes in. By upgrading to a high-quality breather kit, such as those offered by reputable brands like S&S Cycle or K&N Engineering, riders can improve their engine’s performance and longevity. These kits typically include high-flow air filters and larger diameter hoses that allow for better airflow and increased efficiency.

Not only does a crankcase breather kit improve engine performance, but it also helps to keep your bike clean. With a more efficient system in place, less oil will be expelled onto your bike’s exterior components, reducing the need for frequent cleaning and maintenance.

In my experience, investing in a quality crankcase breather kit has

My Buying Guide on ‘Harley Crankcase Breather Kit’

I have been a proud owner of a Harley Davidson motorcycle for the past five years and as any Harley enthusiast would know, maintaining and upgrading your bike is a never-ending process. Recently, I came across the need for a crankcase breather kit for my bike and after doing extensive research and trying out different options, I have put together this buying guide to help my fellow riders make an informed decision.

What is a crankcase breather kit?

A crankcase breather kit is an essential component of a motorcycle that helps in preventing oil leaks, reducing engine drag, and improving overall performance. It works by allowing excess pressure to escape from the engine’s crankcase, thus preventing oil from being forced out through seals or gaskets.

Why do you need a crankcase breather kit for your Harley?

If you own a Harley Davidson motorcycle, you know that these bikes are known for their powerful engines. However, with great power comes great responsibility, and it is crucial to keep your engine well-maintained to ensure its longevity. A crankcase breather kit helps in keeping your engine running smoothly by reducing oil leaks and improving performance.

Factors to consider before buying a crankcase breather kit

  • Type of bike: The first thing to consider when buying a crankcase breather kit is the type of Harley Davidson bike you own. Each model has its own unique specifications and requirements, so make sure you choose a kit that is compatible with your bike’s make and model.
  • Material: Crankcase breathers are usually made from aluminum or steel. Aluminum breathers are lightweight but not as durable as steel ones. On the other hand, steel breathers are more robust but may add some weight to your bike.
  • Brand reputation: It is always advisable to go for reputable brands when purchasing aftermarket parts for your motorcycle. This ensures quality and reliability.
  • Budget: Crankcase breather kits come in various price ranges. It is essential to set a budget beforehand so that you can narrow down your options and choose the one that fits your budget without compromising on quality.

Benefits of using a crankcase breather kit

  • Better engine performance: By allowing excess pressure to escape from the engine’s crankcase, a breather kit helps in reducing drag on the engine’s moving parts, thus improving overall performance.
  • No more oil leaks: A crankcase breather kit prevents oil leaks by regulating pressure inside the engine’s crankcase, ensuring that no oil gets forced out through seals or gaskets.
  • Increase in horsepower: With better engine performance comes an increase in horsepower. A properly functioning crankcase breather can help boost your bike’s power output.

Tips for installing a new crankcase breather kit

  • Familiarize yourself with the installation process: Before attempting to install the new breather kit on your own, make sure you understand how it works by reading the instructions carefully or watching tutorial videos online.
  • Cleanliness is key: The installation process involves opening up certain parts of your bike’s engine; therefore, it is crucial to keep everything clean to prevent any debris or dirt from entering your engine during installation.
  • Tighten all connections properly: Make sure all connections are tightened securely after installing the new breather kit to avoid any potential leaks or issues while riding.

In conclusion

A quality crankcase breather kit can significantly improve the performance of your Harley Davidson motorcycle while also ensuring its longevity. By considering factors such as compatibility with your bike model, material used, brand reputation, and budget before making a purchase, you can choose the best option that meets all your needs. And remember to follow proper installation techniques for optimal results!
